WATER-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 591,120, dated October5, 1897.. Application fil d November 13,1896. Serial No. 611,967. (Noas.)

To all whom it may concern:

Be it known that I, JAMES M. SHERMAN, a citizen of the United States,residing at Golumbia, in the county of Booneand State of Missouri, haveinvented a new and useful Water-Nozzle, of which the following is aspecification.

This invention relates to watennozzles especially designed for use inthe emergency of 'fire; and it has for its object to construct a nozzleof this character adapted to be mounted in a fixed position withrelation to a standpipe or other source of water-supply, so as to bealways ready for use, while at the same time so constructed as to permitof being adj usted so as to discharge a stream of water;

in any desired direction without interfering with the free passage ofthe water through the nozzle.

With these and other objects in view, which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts, hereinaftermore fully described, illustrated, and claimed.

In the drawings, Figure 1 is a side elevation of a water-nozzleconstructed in accordance with this invention and shown in its ap pliedposition for use. Fig. 2 is a longitudinal sectional View of the nozzle.Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2.

Referring to the accompanying drawings, the numeral 1 designates awater-nozzle, essentially comprising a swiveled pipe-section 2 and abifurcated pivotal nozzle member 3, communicating with the pipe-section2; and pivotally joined thereto in the manner to be presently described.The swiveled pipe-section 2 is bent intermediate of its ends to form anelbow, with the upper portion thereof disposed in an approximatelyhorizontal plane, while the lower portion is disposed approximately in avertical plane, and the lower end of the elbow-pipe section or member 2of the nozzle has fitted fast thereon an exterior packing-collar 4:,provided at its lower edge with an outturned flange 5, turning on theinterior annularbearing-seat 6, formed within the bearing-cup 7 of thestationary or fixed coupling-head 8. The stationary or fixedcoupling-head 8 is provided at its lower side with aninteriorly-threaded neck 9, fitted on one end of a stationary stand-pipe10, leading to any point within a building where it is desired to locatethe water or fire nozzle, and said pipe 10 is provided adjacent to itsconnection with the coupling-head 8 with a suitable cut-off orcontrolling valve 11, which is manipulated when it is desired to directthe Water threugh the nozzle or to cut off the flow therefrom; y l

The bearing-cup 7, at the upper side of the head 8, issufliciently largeto loosely receive therein the lower end of the pipe-section 2 with itsattached collar 4:, and at its upper edge the cup 7 is provided with aplurality of offstanding bolt-ears 12, with which are adapted to bealined corresponding bolt-ears 13, projected laterally at intervals fromthe periphery of ringland 14, loosely encircling the pipe 2 above thecollar 4, and provided with a depending beveled packing-flange 15,

working into the space between the collar 1 and the sides of the cup 7to provide for tightly compressing in this space the packing material16, which serves to maintain a water-tight connection between thepipe-section 2 and the head 8,in which it is swiveled. Thevertically-alined bolt-ears 12 and 13 are connected by the bolts 17,which maybe adjusted readily to compress the packing 16, and removedwhen it is desired to repair the connection between the pipe-section 2and the head 8.

The bifurcated pivotal nozzle member 3 ofv the nozzle-body essentiallycomprises an eX- teriorly-threaded coupling-neck 18 and a pair ofoppositely-located tubular twin branches 19, merging into the neck 18and provided therein with transverse openings 20, disposed in precisealinement with the threaded discharge-openings21, formed in oppositesides of the elbow-pipe section 2, at the upper end thereof, which isdisposed within the bifurcation of the member 3 between the branches 19thereof. The oppositely-located side openings 21 of the pipe-section 2are threaded to detachably receive therein the trunnion bushing-rings22, exteriorly threaded to engage the threads of the openings 21 andflanged at their outer edges, as at 23, which flanges 23 bear againstpackingv 23 and pivotally engage with the flanged inner sides of theopenings in the tubular branches 19, and the outer sides of saidopenings 20 are interiorly threaded to detachably receive therein theeXteriorly-threaded closing-caps 24, which, I

" fixed coupling-head provided at its lower side when removed, provideaccess to the bushings 22 when the two members of the nozzle are beingassembled or taken apart, as will be readily understood, and at thispoint it will be' observed that the bushings 22 form trunnions for themember 3 to provide a pivotal connection between such member and thepipe-section 2, so that the member 3 may be swung upward or downward,according to the direction in which it is desired to point thedelivery-spout 25, which 'is detachably fitted on the threadedcoupling-neck 18 of the said member 3.

I NVhile the pivotal mounting of the member 3 permits of the swingingadjustment thereof in the manner explained, the swiveling of thepipe-section 2 to the head 8 permits the whole nozzle to be oscillatedor swung on its axis to any position required, thereby providing a greatvariety of adjustments for the nozzle to render the same especiallyuseful in the emergency of a fire.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described the invention,what is claimed, and desired to besecured by Letters Patent, is-

A water-nozzle comprising a stationary or with a neck, and at its upperside with a bearing-cu-p' formed with a horizontal interior annular fiatseat 6, an elbow-pipe section, an exterior packing-collar 4, fitted faston the lower end of the elbow-pipe section and provided at its loweredge with an outturned flange 5, turning on the interior seat 6, packingfilling the space between the packing-col- ;lar and the sides of thecup, a ring-gland loosely encircling the elbow-pipe section and providedwith a depending flange working within the bearing-cup on the packingtherein, an adjustable bolt connection between the gland and thebearing-cup, and a pivotal nozzle member pivotally joined to andcommunicating with the upper end of the elbowpipe section, substantiallyas set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
